The new species Myrmeleomastax wideis sp. nov. is similar to Myrmeleomastax pulvinella Yin 1984 from Amdo (Tibet) region, China from which it differs by the characters presented in the Table 1 below. Etymology. The specific epithet is named for a distinct character of this species, because the width of mesosternum of this species is distinctly wider than other species in this genus., Published as part of Qiu, Shaoting, Xu, Sheng-Quan & Huang, Huateng, 2021, A synoptic review of Gomphomastacinae (Orthoptera: Eumastacoidea) from the Qinghai-Tibet plateau with a description of new species, pp. 296-300 in Zootaxa 4903 (2) on pages 298-300, DOI: 10.11646/zootaxa.4903.2.9, http://zenodo.org/record/4567417, {"references":["Yin, X.
